2) Interface numbering rule
AR 46 interfaces are numbered in three dimensions. The rules are as follows:
z
The interfaces are numbered in the
interface-type X/Y/Z
format, in which,
interface
specifies the interface type (as serial, asynchronous, ethernet or ATM, etc.),
X
specifies the slot number,
Y
specifies the pinch board number (or is fixed as 0
when there is no pinch board), and
Z
specifies the interface sequence number.
z
As shown in the above figure, different interfaces of an interface module share the
same slot number X.
z
For every interface, Y starts from 0 and Z indicates the interface sequence (from
left to right) on the interface module.
z
For example, 1FE and 2FE modules are installed in SLOT1 and SLOT2 of AR
46-20 Router respectively. The Ethernet ports are arranged as follows:
z
Fixed Ethernet ports are Ethernet 0/0/0 and Ethernet 0/0/1;
z
Ethernet port of 1FE module is Ethernet 1/0/0;
z
Ethernet ports of 2FE module are Ethernet 2/0/0 and Ethernet 2/0/1.
